Which describes the correct way to convert minutes to hours?

To convert time to just hours:

2 hours is 2 hours * (1 hour/ 1 hour) = 2 hours

45 minutes is 45 minutes * (1 hour / 60 minutes) = 45/60 hours = 0.75 hours

45 seconds is 45 seconds * (1 hour / 3600 seconds) = 45/3600 hours = 0.0125 hours

Adding them all together we have 2 hours + 0.75 hours + 0.0125 hours = 2.7625 hours

Step-by-step explanation:

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
